Title: A fluid pressure control valve
IPC: F15B13/06
Filed: 1963-11-08
Abstract: 1,046,873. Valves. WAGNER ELECTRIC CORPORATION. Nov. 8, 1963 [April 23, 1963], No. 44123/63. Heading F2V. Upon applying a manual force to the operating plate 77 of tandem valves in a dual-brake system, a piston 66 is moved against a spring 70a to engage an extension 70 with a movable closure element 63 to close an outlet 24 from an exhaust port 75. Concomitantly the spring 70a displaces a piston 41 against a spring 65 to cause a piston extension 50 to abut a second movable-closure element 38 and disconnect a second outlet 24 from a second exhaust port 31. Further motion of pistons 66, 41 moves elements 63, 38 from seats 58, 22 and place inlets 26, 27 in communication with the outlets 24, 25, respectively. The fluid pressures metered by elements 63, 38 are made equal by balancing the forces of springs 64, 70a and 39, 65 as well as the fluid pressures in the chambers 57 and 19 tending to seat the valve elements 63, 38. Sequential instead of simultaneous operation of the valves is effected by unbalancing the spring and fluid pressure forces. When the reaction force in a chamber 68 equals the manually applied force the pistons 41, 66 move upwards so that the elements 63, 68, extensions 70, 50 and seats 58, 22 are in a " lapped " condition; the reaction force acting through the spring 76 provides the operator with " feel ". Should either system fail the other one can still be operated with only a small lost-motion of the input manual force. Either of the exhaust ports 75, 31 may be blanked-off, the remaining port serving both valves. In a modification, the upper valve element 63 and its seat 58 are part of the piston to which the input manual force is applied whilst the extension 50 is located on piston 41. In a further modification, the element 38 and seat 22 are part of piston 41 whilst extension 50 is fixed and forms the valve casing around the exhaust port 31.

Abstract: 1,130,210. Printing and stamping press. A. APICELLA. 6 Oct., 1966, No. 44715/66. Heading B6C and B6J. A reciprocating press for manufacturing labels simultaneously applies heat sealable material to prints upon, and cuts a web; the heat sealable material is supplied from a second web running at right angles to the first web, the two webs being stationary and juxtaposed during printing and application of the heat sealable material by stamping. A press according to the invention is illustrated in Fig. 1, wherein the main frame 2 contains a reciprocating piston member 4 driven by conventional motor and gearing, and both the piston member 4 and the upper frame 3 contain pluralities of corresponding dies 10, 11, 12 and 10<SP>1</SP>, 11<SP>1</SP>, 12<SP>1</SP>, the upper dies 11, 12 being inked by rollers 13a and 13b.

Abstract: 930,301. Forming non-woven fabrics. COURTAULDS Ltd. Dec. 29, 1961 [Dec. 30, 1960], No. 44728/60. Class 42 (2). [Also in Group IX] Cellulose fibres are crimped, impregnated with a latent setting or cross-linking agent and formed into a felt, batt, wadding or other non- woven fabric. The setting or cross-linking agent may be incorporated into the fibres at any stage in the manufacture of the crimped fibres or non-woven fabrics and should preferably be cured after formation of the fabric. As setting agent there may be used a water-soluble condensation product derived from formaldehyde and some such substance as urea or melamine. Other agents are methylol derivatives obtained from the action of formaldehyde on nitrogenous compounds containing two hydrogen atoms capable of being replaced by methylol groups, e.g. dimethylol ethylene urea, dimethylol-5-(hydroxyethyl)-triazone, dimethylol acetylene diurea, dimethylol-glyoxal-diurea, methylated trimethylol melamine, or methylated dimethylol urea. Magnesium chloride hexahydrate may be employed as a catalyst. The amount of setting agent by weight of untreated fibres is preferably 3-10%, or at most 15%. Webs of crimped, impregnated fibres may be formed by carding and several webs may be superposed, as by cross-folding and laying down on a transverse moving lattice, followed by needling at 1000 penetrations per square inch. Examples utilizing viscose fibres are described but natural cellulosic fibres may be used.

Title: Lamp adjusting device for optical projectors
IPC: G03B21/20

Abstract: 977, 388. Projection lamp adjustments. VOIGTLANDER A. G. Dec. 30, 1960 [Dec. 30, 1959], No. 44857/60. Heading G2J. The lamp in an optical projector is vertically movable between fixed abutments and is held in predetermined positions by catches. As shown in Figs. 3 and 4 a carrier 20 supporting lamp holder 7 is frictionally held by springs 25 against an intermediate wall 21 of the projector; piris 24 moving in a slot 22 and aperture 23, of wall 21 providing lateral anchorage and serving as abutments when carrier 20 is vertically adjusted, so that in an upper position the filament of a lowpower (150 watt) lamp will lie on the optical axis 10 and, when a larger high-power (300 or 500 watt) lamp is used, its filament 8 can be brought irito the optical axis by lowering carrier 20 an amount 9, the two positions of the carrier 20 being defined by notches 26 and a spring catch 27. Carrier 20 may be manually adjusted directly, or, as shown, by a pivoted rod 29 connected to lower pin 24. An indicator sector 37 pivoting with rod 29 brings into a viewing window 38 an indication of the lamp-size appropriate to a particular setting of carrier 20. Alternatively, marks may be provided opposite each position of the knurled head 34. The lower pin 24 is attached to a block 28 having a tapped bore through which extends a threaded portion of rod 29. so that rotation of the latter by means of knurled head 34 can effect some lateral movement of carrier 20, the lower guide aperature 23 being enlarged laterally to accommodate such movement. A switch 42 in the lamp circuit can be closed either by an azur 43 of carrier 20 when the latter is in upper (low-power lamp) position, or when carrier 20 is in the lower position, by a projection 40 carried on a blower assembly 39 which must therefore be inserted before a high-power lamp can operate. The embodiment of Fig. 7 allows manual operation of the lamp switch 42, the latter being mounted on a plate 44 guided by a pin and slot 45 depression of button 46 closing the switch when pin 41 strikes azur 43, or when carrier or projection 40 as the case may be. A spring latch 48 retains the switch assembly in this position until button 46 is moved in the direction 51 whereupon latch 47 clears the underside of the casing and spring 49 urges button 46 outwards.

Title: Detection circuit for significant peaks of speech signals
IPC: G10L25/90
Filed: 1976-11-01
Abstract: A detection circuit for the significant peaks of a speech signal, comprising first and second detectors respectively for detecting the positive and negative peaks of said speech signal. Each of these detectors is followed by a peak charging circuit comprising a first integrator having a relatively large discharge time constant and a comparator comparing the detected speech signal and the output signal of said first integrator. Each peak charging circuit comprises in addition a second integrator having a relatively small time-constant. The discharge of the first integrator is effected up to a voltage equal to the output voltage of the second integrator, and the discharge of the second integrator is effected down to a voltage depending on the output voltage of the first integrator. The two integrators of each peak charging circuit provide a non-exponential decreasing signal which has an inflection point following a significant peak in the original speech signal.

A pulse circuit comprises a series charge storage diode D1 followed by a shunt-charge storage diode D2 connected between input and output terminals I, O and impedances connecting both terminals to reference potentials, D1 having a longer storage time than D2. During the initial positive-going portion of an input pulse or sine wave both diodes conduct in the reverse direction due to charge storage. Diode D2 discharges and becomes non-conductive, first allowing the output to steeply rise to the input level but shortly afterwards D1 becomes non-conductive, bringing the output steeply down again. Bias circuits R1 and R2 (which may be omitted, Figs. 1 and 2, not shown) adjust the storage times and thus the pulse width. L1 may be variable.
